Summarize last N commit messages.
AI agents call summarize_commit_messages to retrieve information from GitHub PR Template Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and summarizes existing commit messages from git history. It is a read-only operation with no side effects — it retrieves historical data and produces a summary. Misuse potential is minimal as it only surfaces already-existing information.
